Welding MIG/MAG
MIG/MAG welding is a versatile technique suitable for both thin sheet and thick section components. An arc is struck between the end of a wire electrode and the workpiece, melting both of them to form a weld pool. The wire serves as both heat source (via the arc at the wire tip) and filler metal for the welding joint. The wire is fed through a copper contact tube (contact tip) which conducts welding current into the wire. The weld pool is protected from the surrounding atmosphere by a shielding gas fed through a nozzle surrounding the wire. Shielding gas selection depends on the material being welded and the application. The wire is fed from a reel by a motor drive, and the welder moves the welding torch along the joint line. Wires may be solid (simple drawn wires), or cored (composites formed from a metal sheath with a powdered flux or metal filling). Consumables are generally competitively priced compared with those for other processes. The process offers high productivity, as the wire is continuously fed.
Manual MIG/MAG welding is often referred as a semi-automatic process, as the wire feed rate and arc length are controlled by the power source, but the travel speed and wire position are under manual control. The process can also be mechanised when all the process parameters are not directly controlled by a welder, but might still require manual adjustment during welding. When no manual intervention is needed during welding, the process can be referred to as automatic.
The process usually operates with the wire positively charged and connected to a power source delivering a constant voltage. Selection of wire diameter (usually between 0.6 and 1.6mm) and wire feed speed determine the welding current, as the burn-off rate of the wire will form an equilibrium with the feed speed.
Metal Transfer Mode
The manner, or mode, in which the metal transfers from the electrode to the weld pool largely determines the operating features of the process. There are three principal metal transfer modes:

Welding TIG/WIG
Using the TIG/WIG technology of welding in controlled atmosphere we weld all kinds of weldable structural steels, further - corrosion-proof steels, hardly weldable materials (free-cutting steels and others) and their combinations. We use the advanced digital power supplies for the TIG/WIG welding.
Traditional manual workplaces and automated workplaces for rounded welds are available for welding by the TIG/WIG method. The welds in automated workplace for rounded welds are performed as without additional material, as with it.
Due to our technological equipment, we offer the combination of TIG/WIG welding, ultrapulse welding (UP welding) and capillary fitting to our customers. By the use of more technologies in one part – optimum technology for each connection – a high productivity, very good and repeatable quality and very favorable production costs are achieved. Using the combinations of connection technologies also very sophisticated and accurate parts are produced.
With our own capacities or externally, we also assure following operations for welders:
